How long do you keep a router in production?
What is your cycle for replacement of equipment?
For a PC, you usually depreciate it over 3 years, and can make it last 5
years, but then you are stretching the functionality, especially if you
upgrade the OS, tho it is not uncommon to see companies still on XP and
IE6.
Hell, we still have Windows 2000 and IE6.
People tend to want/expect faster graphics performance, faster CPUs, more
RAM for bigger (or more bloated) applications.
A router handling T1 aggregation (i.e. cisco 7206, PA-MC-T3, M13 mux) 10
years ago will still handle T1 aggregation today (assuming you still have
T1 customers). Over that time period, the only major change is that with
routing table growth, routers that were able to handle full routes no
longer can...so you either have to upgrade the NPE board to one that can
hold 512MB or more or give up full routes. And with the widebank28 muxes,
you just have to replace the mux controller cards every few years as they
tend to burn out.
